Application filed December 14:, 1907. Serial No. $06,4l99.

of a shafting journal-box constructed according to ,my invention.

This invention relates to that class of )ourvnals in which the series of load-sustaining rollers is A rcperly spaced by intervening spacing rollers of smaller diameter, and the object of the present invention is to improve that type of bearing and rend er it cheaper to manufacture and assemble, as more fully hereinafter set forth.

Referring to the drawings by reference characters, c designates the load-sustaining rollers having contact with the interior of the box l) and the exterior of the shaft c, this box being held against endwise movement on the shaft by means of thrust collars d. on the shaft said thrust collars being provided near their outer edges with a ball raceway reoeiving balls against which the ends of the box abut. l have shown the invention ap )lied to a journal box for shafting but it wil be understood that the invention is a plicable to car and other journals without di) of the essential parts of this invention.

The usual spacing rollers e are arranged between the load-rollers and have their ends as usual projecting beyond the load-rollers and provided each with an annular groove in which engages an annulartrack j surrounding the shaft but unconnected thereto. These grooved ends of the spacing. rollers are confined upon the tracks by the usual loose rings g resting on the grooved necks of the rollers radial alinement with the tracks.

Each track is provided with or formed on a sleeve 7i which extends into an annular recess in the adjacent face ofthe thrust collar, this recess in the thrust collar` being-large enough to form in conj onction lwith said sleeve h a raceway for a series of balls fl, the balls bearing upon the outer face or periphery ef the sleeve and the inwardly facing shoulder j teration formed by the recess in the collar. The sleeve h at a point between the track flange andits other end is provided with a radial flange k which forms another wall of the ball raceway. A

It will be observed that the tracks f are not fastened to the shaft but are on theother hand free to rotate independently thereof as Well as independently of the box and the rollers in other words, each track flange is maintained in a sort of floating condition, being supported on the balls i. which balls also, by reason of the radial flange take up f the end thrust of the floating tracks, i bearing of this type will be easy to maire and assemble and at the same time it may he made as accurately as that type of bearing in which the tracks are fastened tothe shafting or to the box.

Having thus fully described my invention, what l claim as new and desire to secinfo by Letters Patent, is :e-l

1. ln combination, a shaft, a befr, a of load-sustaining rollers and a series of spaning rollers, the ends of thev latter being grooved, thrust receiving collars on the shaft each being provided with an annular groove adjacent to the shaft, sleeves loosely suis rounding the shaft and each l .f1-ving one end. entering said groove in the adjacent llirust collar, said sleeve carrying a track flan?" t its other end and a radial flange inter its ends, a series of balls confined sleeve and said radial flange in the g the lthrust collar, and confining ringL ing the grooves in the spacing rollers. "72. In combination, a box, a shaft, load rollers, spacing rollers having groovcd ends, confining rings engaging these grooves, a floating sleeve loosely surrounding the shaft at 'each end of the bearing, each of these sleeves being provided with flanges forming part of a ball raceway, a series of balls in said raceway, and collars forming the other part of said raceways.

In testimony whereof signature in the presence 0f two witnesses this 2nd day of December 1907.
